Hi, I wanna know how to use OpenSER with redundancy and scaling.
 
Example:
 
the user 1000 can register in ser A.com and in ser b.com.
and the users that have a 1000 as contact can see the PA in the 2 case, ( 1000@a.com and 1000@b.com)  but donīt send the subscriber to 2 users.
 
is this posible ?
best regards
